Subject: [PATCH] Enable "Open With..." action for read-only archives as well

Like "Preview", this should be possible as well, as it doesn't modify
the archive.

This now uses the same condition as for the "Preview" action,
which also has these consequences:
- it's disabled for directories now, where it doesn't work anyway
- it's also disabled when more than one entry is selected, it only
  opened the first one previously

This was actually fixed in commit f1cf10f2 in Ark 15.12, when the
"Open File" action was added.
